About

  • Requires: qryCtg_src_sub, qryCat_Titles
  • Used by: catalog building process (details to be documented)
  • History:
    • 2008-03-15 Building sequence completely rewritten, so presumably this query was created then
    • 2008-04-02 convert blanks to nulls in b.ItOpt_Descr_part
    • 2010-12-29 Added t.ID_Supplier because cat_items now needs that field set.
    • 2011-01-02 Added t.Name (AS TitleName) for the same reason
    • 2016-03-02 This query no longer works, and also shouldn't be needed.
  • Fields:
    • b.ItOpt_Descr_part apparently often comes up as "" rather than NULL, so we have to convert blanks to nulls before testing for null.
